What is the size of the plug? （1/4 Inch ？ 1/8 Inch？ ）

It's a 1/4" plug, but you can buy the 1/4" to 1/8" adapter in order to make it suitable for cell phones.

Nathan, Not sure if I can be of much help. One end of the plug is a standard USB port plug. The other end (which plugs into the helicopter) looks to be about the same size as a 1/8 inch headphone plug.

I believe that I used a 1 1/16" socket. I ordered two of these and one for a spare.

I believe 1/8th inch is the actual measurement. It works with a small jack like I have for all my cellphones, ipod, ipad, etc. Totally standard size.

it is a standard USB plug that sticks out maybe a 1/4 inch or so from the base, it is only slightly larger than the male USB plug part.

It is a standard 1/8" plug size. It will fit a PC and just about any portable MP3 player. No adapter needed.

I don't have an exact measurement but i would estimate between an 1/8 and 1/4 inch.

I do not understand, what you mean by the "size of the adapter"....what adapter?

I have no idea. If you go to sight showing this emitter and enlarge it you can find the exact size of the plug.

It's wired to a 1/8th plug. Honestly, I cannot remember if a 1/4 adapter was included... I have several of those gold 1/4 stereo adapters; I will, however, take a leap of faith and say that it does include a 1/4 adapter. If I'm wrong, then just go to Radio Shack and buy the gold, FLAT 1/8-1/4 inch adapter. Do NOT get the threaded screw-on type adapter. Get the flat one so you have a secure connection--good luck... Best, Evan J.

It is 1/4" & if I remember it has a 1/4" to 3/8" adapter. I use the 1/4" with a long extension and ratchet. Sorry for late reply due to holidays and a good case of the crud. GMF

The unit I received has a port, looks like a 1/4". It's plugged, but comes out with some heat and a large hex.

If I measured correctly, it is 3/8ths of an inch. If I measured incorrectly, I'd say it is 1/4 inch. [Wow, I just looked at another answer, and it measured much larger than I did. Mine is from the wall to the outside of the plug, but does not include the slight hump where the actual cord comes off the plug. Still, I measure no more than 1/2".]

I'm not really sure on the size but I can tell you that it is a standard cigarette lighter plug and I used it for a DC TV in an RV. I hope this helps and it has worked perfectly so far.
